i bought these girls at a auction but have no idea what they could be, and any thoughts on ages, any help would be greatly appriecated
Your white one looks about 5-6 wks old and is most likely a white leghorn. Your red picture #1 looks like Red Stars did about 5-6 wks old -- Hope that helps --
The red ones look like RIRs and without have a great reference for size, I would say they are about 9-10wks since they seem to have lost all the downy feathers on their heads, they could be older than that though.
I'm going to guess a white leghorn and Rhode Island Red's that are somewhere around 11 to 15 weeks old. They are also all pullets.
I think they look to be at least 10 weeks old. The red ones are RIR or production reds. The white one is not a leghorn - leghorns have yellow legs.
